Oobleck is a fun, science experiment that behaves like both a liquid and a solid. When you apply pressure, it becomes hard and firm, but when you let it go, it returns to its liquid form. It’s the perfect activity for kids and adults alike! Here’s how to make your own Oobleck at home with just two simple ingredients.
Ingredients:
- 1 cup cornstarch
- 1/2 cup water (adjust if needed)

Instructions:
- Mix the cornstarch and water: In a large bowl, add 1 cup of cornstarch.
- Gradually pour in 1/2 cup of water while stirring. Keep mixing until the mixture reaches the desired consistency.
- Adjust the texture: If the Oobleck is too thick, add a little more water, one tablespoon at a time. If it’s too runny, add more cornstarch.
- Test your Oobleck: You’ll know it’s ready when it feels solid when you squeeze it, but flows like a liquid when you stop applying pressure.
Fun Tips:
- Color it: Add a few drops of food coloring to make your Oobleck colorful!
- Experiment with it: Try quickly tapping or punching the Oobleck to see how it reacts!
- Storage: Keep your Oobleck in an airtight container for reuse. If it starts to dry out, add a little more water.
